Sasha (Gad Elmalai Gad Elmaleh) is a 40-year-old advertising songwriter who is not confused by the so-called 40 years old. Sasha is afraid of commitment, of stable relationships, and for him to be able to do whatever he wants can really be considered alive. This naive personality makes Sasha's friends and relatives suffer a lot, and his mother even keeps the habit of cleaning the apartment and washing clothes for her son. Sasha's headache seems to continue until he meets a beautiful woman named Charlotte (Sophie Marceau Sophie Marceau). Charlotte divorced her husband and worked hard to raise three children on her own. When the spark of love ignites between these two adults with very different personalities, what happens to the story of laughter and tears?
